Granted. By the power of magic, every time you want to download something, the upload speed of every connection in the world is drained and transferred to you. This in effect gives you almost unlimited download speeds, so its really fast.
However, the caveat is that, given that you download from a server and they upload that to you, but during your download, their upload is gone, you effectively can't download anything anymore. Luckily once you stop downloading, their upload returns to normal speeds, so the rest of the world is not affected.
I wish my car had a magic roof that would disappear when I'm in the car and the sun shines, but would magically appear when I'm not in the car or the sun stops shining.
